    Finally under way.There is a small batch of 20 being cast at the moment. The final cost is $390 plus postage. All of this run has been allocated to people by the date they placed their order. If anyone else wants to place an order, I will see if the casting run can be increased but you have to act within a couple of days. You will be required to pay 1/2 deposit to help offset my costs once I confirm things with the foundry.

    I have increased the casting run to 30, they should be back from the foundry in 2-3 weeks.

    Sorry to all those who placed their deposits, still waiting on the iron foundry to finish the castings. Hopefully they'll pull their finger out soon and get on with it. It's been a long wait, all your deposits are being held intact pending the foundry invoice, I will be happy to refund the deposit of anyone who can't afford to wait
    Can't wait for this to be finished, It's holding up a pile of projects I want to get on with. Whatever happened to service and honoured delivery times.

    A few photos of the progress so far, still a few more weeks to finish though. Excuse the quality of the photos. The dovetails are currently being machined, the t-slots are next. Still have the jib screw threads, dial groove and final top and bottom grinding to do.

    The final post before I start delivering these in order of the oldest requested. Only 2 completed so far but hopefully the others won't be far behind. This is the finished look.

    Not taking anymore orders through the forum. All the remaining slides, after the prepaid orders have been filled, will be offered through the website in the normal fashion. There may be 10 or so left over but only half are for the 260, the rest are for the 9" models.

    I follow some of the drawing, Mal.
    But, could we have some text explanation too, please?
    It's not clear to me the need for the nut above the T slot, for example.
    I must have missed that class.

    Although I never claimed to be a machinist, it seems to me that if you hold a flat piece of cast iron between two flat surfaces, the chances of it flexing becomes zero. The shearing forces to tear a slot vertically supported like that would be enormous. Most people would have more sense than to do the wrong thing, I just wanted to cover all bases.
    Does anyone else not understand what is shown in the pdf.

    The theory behind the sandwhich nut and small plate or flange nut has merit on reasonably thin tee slots,another way to transfer the load on the tee slot would be to use a longer than normal tee nut,in this instance a nut around 1 1/2" / 38mm would be good.

    After all the holding stud is only going to be about 3/8" / 10 mm.

    Sorry, but I still don't follow what's being presented.
    May I ask some basic questions?

    - What does the L -shaped piece in the first example represent? Is it the job, or a clamping piece?
    - I understand a long T-nut would spread the load on the slot flanges, but what is the hex nut on top of the table doing, immediately above the T slot?
